Trying to configure eService.
First try to make FAQ on eService. Doing everything by official manual ( Siebel eService Administration Guide Version 8.0 - December 2006/Setting Up the Knowledge Base for Siebel eService ) and no result.

Steps:

1. Configure catalog
2. Configure category
3. Configure solutions

Nothing showing in eService *"Browse the Knowledge Base"* and Top FAQs .

I never worked with this, but perhaps you can use the SQL Log to find out if there are any filters in the background that stop the FAQ's from displaying properly.

I'm not really sure if you can make the eService Object Manager start from the Local Client.
If yes, you can spool the SQL quite easily: Spooling SQL - Using the /S Option to Examine the SQL Generated by Siebel Application [ID 475564.1]

You can also try to spool the SQL directly from the Object Manager.
How Can Tracing Be Increased for the Siebel Object Manager? [ID 477897.1]
I would only do that on a test environment.

As you noticed, that functionality is very sensitive to names.
That's why I advised to have a look at the SQL, to see if it applies any filters (on the name).
They don't show up as errors, just SQL with a zero record count.
